This model, with just 3 parameters in the hidden sector, \(\gamma , \zeta \)  and \(\tilde{\mu }\) , has been used in the literature in the context of SM extensions, identifying the visible scalar field \(\phi \) 
with the Higgs field and \(\eta \)  with a dark matter scalar. By requiring the energy density to account for the observed dark matter relic abundance and successfully satisfy the existing observational constraints, it is possible to find the viable values for these parameters [1]}, [2]}.
